Study performed on two lavender oils from different Romanian areas

Two lavender oils, having the same genetic material, were extracted in identical conditions (water steaming from Lavandula angustifolia flos). Differences consisted in the age of the culture and in the region of cultivation. The lavender oils were assayed for their composition using GC-MS and HPTLC [1]. GC-MS analysis was performed on a TRACE TR- 5MS capillary column, 5% phenyl polysilphenylene-siloxane, within the range 30–650 m/z. Identification was based on the mass spectrums from NIST library collection. HPTLC analysis was performed on silicagel, using ethyl acetate: anhydrous acetic acid: formic acid: water (72:7:7:14) as a mobile phase, and a migration distance of 8 cm.
